In an emergency, who is responsible for briefing the ABP's for the L2 and R2 doors?

In an emergency situation, the responsibility for briefing the Able-Bodied Persons (ABPs) for the L2 and R2 doors typically falls to the No 2 crew member. This is crucial because the No 2 is positioned in a key position in the cabin, allowing them to effectively manage the responsibilities associated with those exits.

Briefing the ABPs is essential in an emergency response, as it ensures that able-bodied individuals are informed about their roles and what actions they should take to assist in the evacuation process. The No 2's role includes ensuring that the ABPs are clear on when and how to operate the doors, enhancing the overall safety and efficiency of the evacuation.

The other crew members, while also trained and capable, do not have the designated responsibility for this specific task, which is why the No 2 is the correct answer here. The roles of each crew member are structured to ensure that all responsibilities are covered during an emergency evacuation, making the crew's coordination vital.
